Hello,
There is something I have been wondering about for years and no one could tell me whether it was normal or not, they do not seem to understand, the only thing I have been told is "you must have been hit by dust" which makes no sense.
So, when I go to bed and think before I eventually fall asleep, I sometimes have involuntary movements. Sometimes I startle for no reason, or it's just my arm or leg which makes a quick movement (like a twitch). I also see a bright light during a second and when it happens I hear a noise.
It prevents me from falling asleep because I suddenly feel very awake and not sleepy at all.
I follow a regular sleep schedules, I rarely go to bed after midnight though it may happen when I do not have to work (during the holidays or on saturday only).
I have always had that, it was worse when I was younger though (happened a lot before I fell asleep) and apparently no one in my family has ever experienced that. I do not think it's life threatening but the sensation is very strange sometimes, it can feel as if everything in my body had stopped working during a very short time (less than a second) and start working again suddenly.
I wonder if it can be linked to restless leg syndrome because I seem to have it (but it's usually more than the legs and I have "crisis" during the day sometimes which can make me act violently against a pen XD).
